4.2.6.4.1 VLAN Support
The VLAN Support menu enables defining the parameters related to the IEEE
802.1Q compliant VLAN aware (Virtual LAN aware) feature of the units. Each
VLAN includes stations that can communicate with each other, but cannot
communicate with stations belonging to different VLANs. The VLAN feature also
provides the ability to set traffic priorities for transmission of certain frames. The
information related to the VLAN is included in the VLAN Tag Header, which is
inserted in each frame between the MAC header and the data. VLAN
implementation in BreezeACCESS 4900 units supports frame routing by port
information, whereby each port is connected to only one VLAN.
The system also supports the 802.1 QinQ standard, which defines the way to have
2 VLAN tags (double-tagged frames). This procedure allows an additional VLAN
tag, called Service Provider VLAN tag, to be inserted into an existing IEEE 802.1Q
tagged Ethernet frame. This is a solution to transport multiple customers' VLANs
across the service provider's network without interfering with each other.
The VLAN Support menu includes the following parameters:
 VLAN Link Type
 VLAN ID - Data (SU only)
 VLAN ID - Management
 VLAN ID - Service Provider (SU only)
 VLAN Forwarding
 VLAN Relaying (AU only)
 VLAN Traffic Priority
 VLAN QinQ Protocol Ethertype (Hex)
 VLAN Extended Access (SU only)
 VLAN ID - Extended Trunk (SU only)
